Heat treatment is an indispensable core process in bearing housing manufacturing, which significantly improves key indicators such as mechanical properties, wear resistance, and fatigue resistance by changing the internal structure of the material.

[0003] In existing technologies, the bearing housing is typically heated using eddy current conductors in an electromagnetic induction heater. However, these conductors are usually exposed on the outside, making it easy for workers to come into contact with them during installation, which could pose a hazard. Utility Model Content

[0004] This utility model proposes a heat treatment device for bearing housing processing to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bearing housing processing heat treatment device, comprising an electromagnetic induction heater, wherein the electromagnetic induction heater is placed on the ground to provide support for the whole, the two ends of the eddy current conductor are fixedly connected inside the electromagnetic induction heater, wherein the alternating current inside the eddy current conductor can drive the eddy current conductor to heat up, a cylinder is fixedly connected to one side of the eddy current conductor, wherein the cylinder is located directly below the eddy current conductor, a placement plate is located at the output end of the cylinder, wherein the placement plate can fix the bearing housing, and a protective device is installed on one side of the electromagnetic induction heater, wherein the protective device can protect the eddy current conductor.

[0006] The effect achieved by the above components is as follows: when the bearing housing needs to be heated, the operator places the bearing on the placement plate. At this time, the protective device wraps the eddy current conductor to prevent the operator's hand from accidentally touching the eddy current conductor. Then, the cylinder is opened, and the cylinder moves the placement plate and the bearing housing upward. The bearing housing enters the interior of the eddy current conductor. The alternating current inside the electromagnetic induction heater generates an induced current in the eddy current conductor, causing the eddy current conductor to heat up itself. The eddy current conductor heats the bearing housing on the placement plate.

[0007] Preferably, the protective device includes two side plates, which are detachably mounted on one side of the electromagnetic induction heater by means of bolts. A common protective plate is provided between the two side plates, and two sliding plates are installed on both sides of the protective plate. The sliding plates have a "T" shaped cross section. The side plates have grooves corresponding to the sliding plates, and the sliding plates and grooves are matched in size. The bottom plate is installed at the bottom of the side plates, and the bottom plate is located directly below the grooves.

[0008] The effect achieved by the above components is as follows: Before using the electromagnetic induction heater, the operator first installs the two side plates to one side of the electromagnetic induction heater with bolts. Then, the operator moves the protective plate, and the sliding plates at both ends of the protective plate are inserted into the sliding grooves of the side plates. Finally, the protective plate is pressed against the base plate, thus achieving the effect of installing the protective plate. The two side plates and the protective plate set by the protective device wrap around the eddy current conductor, achieving the effect of protecting the operator's hands and preventing the operator's hands from accidentally touching the eddy current conductor, thereby preventing hand injuries.

[0013] Preferably, a counterweight is fixedly connected to the bottom of the protective plate, and the size of the counterweight is adapted to the size of the protective plate.

[0014] The effect achieved by the above components is that, under the action of the counterweight, the slide plate on the protective plate can slide inside the slide groove of the side plate, which brings convenience to the staff.

[0015] Preferably, the upper surface of the side plate is provided with an auxiliary device, the auxiliary device including a pad, the pad being fixedly connected to the upper surface of the side plate, a spring being fixedly connected to one side of the pad, and a clamping plate being fixedly connected to the other end of the spring, the clamping plate having a trapezoidal cross-section, wherein the clamping plate is located on the upper surface of the slide groove.

Then, the sliding plate of the protective plate inserts into the groove of the side plate. When the sliding plate of the protective plate is fully inserted into the groove of the side plate, the clamping plate moves back to its original position under the action of the spring's return force. The clamping plate covers the groove of the side plate, thus achieving the effect of limiting the side plate of the protective plate. The auxiliary device achieves the effect of limiting the protective plate, preventing the protective plate from shaking when the electromagnetic induction heater is working.

[0017] Preferably, a handle is fixedly connected to the upper surface of the card plate, wherein the surface of the handle is provided with anti-slip texture.

The sliding plate 53 presses against the inclined surface of the clamping plate 63, causing the clamping plate 63 to move towards the pad 61. The spring 62 deforms, exposing the sliding groove 54 below the clamping plate 63. Then, the sliding plate 53 of the protective plate 52 inserts into the sliding groove 54 of the side plate 51. When one end of the sliding plate 53 of the protective plate 52 abuts against the base plate 55, the clamping plate 63 moves back to its original position under the restoring force of the spring 62. The clamping plate 63 covers the sliding groove 54 of the side plate 51, achieving the effect of protecting the protective plate 52 and the side plate 51. The device provides a limiting effect.

At this time, the protective plate 52 and the side plate 51 wrap around the eddy current conductor 2, preventing the worker's hand from accidentally touching the eddy current conductor 2. Then, the cylinder 3 is opened, and the cylinder 3 moves the placement plate 4 and the bearing housing upward. The bearing housing enters the interior of the eddy current conductor 2. The alternating current inside the electromagnetic induction heater 1 generates an induced current in the eddy current conductor 2, causing the eddy current conductor 2 to heat up. The eddy current conductor 2 heats the bearing housing on the placement plate 4. The two side plates 51 and the protective plate 52 of the protective device 5 wrap around the eddy current conductor 2, achieving the effect of protecting the worker's hand and preventing the worker's hand from accidentally touching the eddy current conductor 2, thus avoiding hand injury.
